From an interview with German Fernandez on Dyestat.com:
6) There are a few "German Fernandez Stories" floating around the internet. One is that you stopped to tie your shoe at your league cross country finals after 800m, still hitting the mile at 4:45, and finished in 14:42. Another is that less than four months after returning from knee surgery, you ran 4:05 for 1500 then came back the next day with a 1:09 half marathon. True or false? And can you add a few details?
GF: Yes, I had to stop to tie my shoe at the league finals after 800 meters, and it was scary because I had never been in that situation before. Maybe that was why I ran so fast. And last year, four months after my surgery, I ran 4:05 for a 1500 and then, the next day, a half marathon in 1:09, which I really didn't enjoy. It was supposed to be my easy long run with my girlfriend Georgina Arnold. I started off at 6:30 pace, and then after that it became a race. I picked it up to a 5:19 pace, catching up to the leaders, and outkicked the last two older guys at the end to win it. After I finished, they told me I made it to nationals, and I'm like, "What? I can't go— if my coach finds out what I just did, he'll kill me (no joke)." So I gave my spot at nationals to the fourth guy who finished. Man, my legs were so burned out that I couldn't even walk. It was horrible. It took me two weeks to recover from that race, so yeah, it was pretty intense.
